Geranium plant named &#39;Zonabriscal&#39;

ABSTRACT

A new  Geranium  plant particularly distinguished by the deep scarlet flower color, round plant structure with medium strong branching, green foliage with medium zone, and medium vigor.

LATIN NAME OF THE GENUS AND SPECIES OF THE PLANT CLAIMED

Pelargonium zonale (L.) L'Hérit. ex Ait

VARIETAL DENOMINATION

‘Zonabriscal’

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Geranium, botanically known as Pelargonium zonale (L.) L'Hérit. ex Ait, and hereinafter referred to by the variety name ‘Zonabriscal.’

‘Zonabriscal’ is a product of a planned breeding program. The new cultivar ‘Zonabriscal’ has large, semi-double flowers, is relatively vigorous, but with a well-branched growth habit, and has good heat resistance.

‘Zonabriscal’ originates from a hybridization in a controlled breeding program in Enkhuizen, The Netherlands. The female parent was an unpatented hybrid seedling identified as no.1185 with deep scarlet red color and medium vigor with nice zone. The male parent of ‘Zonabriscal’ was an unpatented hybrid unknown seedling with unknown characteristics.

‘Zonabriscal’ was selected as one flowering plant within the progeny of the stated cross in 2001 in a controlled environment in Enkhuizen, The Netherlands.

The first act of asexual reproduction of ‘Zonabriscal’ was accomplished when vegetative cuttings were taken from the initial selection in the Fall of 2001 in a controlled environment in Enkhuizen, the Netherlands.

Horticultural examination of plants grown from cuttings of the plant initiated in April of 2002 in Enkhuizen, The Netherlands, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Zonabriscal’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘Zonabriscal’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length.

BRIEF DESCRIPTION OF THE NEW VARIETY

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘Zonabriscal’ with colors being as true as possible with an illustration of this type. The photographic drawing shows a flowering potted plant of the new variety.

DETAILED BOTANICAL DESCRIPTION

The measurements were taken in Enkhuizen, The Netherlands, in August 2005 on plants that were growing in window boxes. Culture of these plants started mid February, 2005 in the greenhouse; plants were transferred to window boxes mid May, 2005.

BRIEF SUMMARY OF INVENTION

The following observations, measurements, and comparisons describe plants grown outside in Enkhuizen, The Netherlands. The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Geranium as a new and distinct variety.
